The NSW government has issued a "notice of default" to CGU, the lead contractor for Sydney's M6 motorway project, demanding they resume work by May 1st. The $3.1 billion tunnel project, which is 90% complete, has been delayed due to sinkholes and geological issues. CGU reportedly wants to withdraw from the project, citing a "reverse fault" as a major obstacle.
